Abstract:Runoff was collected from 4 roofs, 3 courtyards and 6 streets on an experimental catchment in central Paris, and analysed for SS, VSS, COD, BODS, hydrocarbons, heavy metals both as regards dissolved and particles fractions. Whereas street runoff showed important SS, COD and hydrocarbon loads, roof runoff was noticeable for its high concentration of heavy metals...

Greener Waste Technology has been working with a utility company to combat the effects of flooding on a filter bed works. The works in question is low lying and next to a river which recently burst its embankment and flooded the filter beds entirely. The flood distributed large volumes of silt and mud onto the filters blocking the beds and starving the indigenous bacteria population of oxygen which prevented the filter beds from operating efficiently.
The utility needed a fast and efficient solution to remove...

In this study, a pilot-scale integrated constructed wetland with vertical flow (VF) and horizontal flow (HF) in series was designed and investigated to evaluate sewage wastewater treatment capacity. The VF unit was planted with Canna indica and was 1.2 m long, 1.2 m wide, and 1.2 m high; whereas the HF unit contained Colocasia esculenta and was 3.0 m long, 1.0 m wide, and 1.0 m high. The system was operated under different hydraulic loading rates (HLRs) of 0.1, 0.2, and 0.15 m/d. The effluent concentrations...

Author’s note: The terms mill and plant are used interchangeably in this article to describe an industrial manufacturing unit, such as a Pulp & Paper Mill, Petroleum Refinery, Chemical Processing Plant, Meat & Poultry Processing, etc.
Plant (or mill) outages come in two types – scheduled and unplanned. Scheduled outages are generally annual affairs at roughly the same time each year and are used to conduct maintenance or other work that cannot be performed while the plant is in full operation....
